The following plugin is an alternative for users of Unity 3.5 that need to identify new Apple mobile devices like the iPhone5S and iPhone5C. Using the device model as a string is also a good ideia if your application can download config files from a server or if you are using AssetBundles. This way you do not need to upload a new binary to Apple only to set some settings based on the user device.
The plugin is avaliable at:
